Abstract
We discuss new studies of a multiple quantum well hetero n-i-p-i structure which combines the advantages of multiple quantum wells and doping superlattices. The structure exhibits large changes in its absorption coefficient for intensities of only a few mW/cm2. We have used the spectral dependence of the nonlinear absorption coefficient to deduce photogenerated carrier lifetimes as a function of intensity.
